A hand-held ultrasound imaging transducer assembly designed to be positioned within a surgical site for localized intraoperative imaging applications. It is sometimes referred to as a surgical probe or fingertip probe. It steers, focuses, and detects the ultrasound beam and resulting echoes either mechanically or electronically. This GMDN code includes ultrasound imaging transducer assemblies used with A-mode, B-mode, M-mode, Doppler, colour Doppler (CD), and duplex (combination imaging, Doppler and/or colour flow) scanning capabilities. This is a reusable device.
